Broken patio door in Newmarket: we dispatch 24/7.
Newmarket is roughly a 55-minute run from our Mississauga shop — less if a technician is already in the area — so a truck is usually on site the same day.
Emergency board-up, security and make-safe first — permanent repair scheduled after.
Broken patio door glass in Newmarket
A cracked or shattered pane is the patio door call we get most. The frame, rollers and lock are usually fine, so only the glass unit is replaced — in the door you already have.
Made safe first
After a break-in we come out overnight — to Stonehaven, Glenway or anywhere else in Newmarket — clear the glass and board up the opening so the house can be locked. A crack that still holds waits for a daytime visit.Measured for a new unit
Patio door glass is tempered, usually a double-glazed sealed unit. The new one is made to your panel's size, with Low-E and gas fill if the original had them.Fitted into your existing panel
One visit to measure, one to fit. With the panel out, we check the rollers and weatherstrip too.Don't slide a cracked panel: tempered glass can break all at once. Keep it closed and call us.
Aluminum or vinyl — what the frame changes about a patio door repair in Newmarket
Most sliding patio doors in Newmarket houses have either an aluminum frame or a vinyl one. The parts that wear out are the same kind of part on both. The frame decides how those parts are adjusted, which of them wear out first, and at what point the door is no longer worth repairing.
Fix a dragging or sticking patio door in Newmarket
After a break-in, or if the door will not lock or the glass is broken, call 800-522-6825 — the line is answered 24 hours and we come out overnight to board it up. For a door that drags, grinds, jumps the track, drafts or has fogged between the panes, tell us what it is doing, whether the frame is aluminum or vinyl, and whereabouts in Newmarket you are. A photo of the bottom corner of the sliding panel helps us bring the right rollers.
Common questions about patio door repair
Do you repair patio screen doors?
No. We work on the patio door itself: its rollers, track, lock, handle, weatherstrip and glass. Re-screening and screen-door repairs are a separate trade, and a screen specialist will serve you better for those.
My patio door keeps coming off the track. What is wrong?
Usually one of the rollers has broken or dropped, so that corner of the panel no longer sits on the rail. Less often, the rail itself is dented or worn flat, and the roller can ride over the damaged spot. Stop using the door until it has been looked at. A heavy glass panel that is off its track can fall out of the opening.
There is fog between the glass panes. Can that be fixed?
The seal around the glass unit has failed, and moist air is getting into the space between the panes. That cannot be cleaned out. The cure is a new sealed glass unit made to the same size and fitted into your existing panel. The frame, rollers and lock stay where they are. It takes two visits, one to measure and one to fit.
